Application fi1ed December 12, 1918. Serial No. 266,385.

T all whom it may 00%66'711.

Be it known that l, HERMAN Orrrz, a citi- Zen of the United States,residing at St. Cloud, in the county of Stearns and State ofllllinnesota, have invented certain new and useful Improvements inDetachable Buttons, of which the following is a specification.

The present invention comprehends generally improvements in that classof inventions known as buttons, buckles and clasps and more particularlyhas reference to an improved detachable button.

As the principal object, this invention contemplates the provision of adevice of the above mentioned character the component parts of which aredesigned so as to be quickly applied in position on a garment andmaintained in proper position without necessitating the employment ofindependent securing means.

More particularly, this invention embraces the provision of a device ofthe above mentioned character composed of cooperative receiving andattaching members, of improved construction designed to be clamped inposition on a garment and arranged in detachable engagement with eachother.

Among the other aims and objects of this invention may be recited theprovision of a device of the above mentioned character wherein the partsare few, the construction simple, the cost of production low and theefficiency high.

Other objects, as well as the characteristic features, nature and scopeof this invention will be more readily apparent from the f0llowingdescription taken in connection with the accompanying drawings andpointed out in the claim, forming a part of this specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is an elevational view showing the device applied andlooking toward the outer face of the attaching member,

Fig. 2 is an enlarged transverse sectional view taken on line 2-2 ofFig. 1,

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2 in the directionin which the arrows point, and

Fig. d is an elevational taching member.

Similar characters of reference are emdetail of the atployed in all ofthe above described views, to

indicate corresponding parts.

Referring now, more particularly, to the accompanylng drawings, there isprovided the lmproved detachable button which in the present instancemay be said to consist of a receiving member generallydesignated by thenumeral 1 and an attaching member indicated in its entirety by thenumeral 2 and designed for engagement with a portion 3 of a garmentpreparatory to being engaged with the receiving member 1, the latter inturn being adapted to receive the attaching portion l of the garment orother object to be supported or received by the member 1.

The receiving member consists of a tubular body 5 internally threaded asat 6 while formed with the outer surface of the tubular body at therespective ends thereof and arranged in spaced parallel relation withrespect to each other are outwardly extending disk-like flanges 7, saidflanges coacting with each other and with the body in receiving andretaining the portion 4 or the object to be supported and having theircircumferential edges rounded for convenience and security in grippingthe receiving member between the fingers.

The attaching member 2 consists of a head of a disk-shape from one faceof which projects a concentric and threaded shank 9, the outer portionof the shank being pointed as at 10 to facilitate penetration of theshank through the portion 3 of the garment, while the threaded portionof the shank is subsequently engaged in the correspondingly threadedtubular body so that the head 8 will coact with the adjacent disk-likeflanges 7 for the clamping of the button on the garment. The outer edgeof the head is knurled and rounded as at 11 to facilitate turningthereof though if a very tight engagement is desired a screw driver orthe like (not shown) may be engaged in the transverse kerf 12 in theouter face of the head, as is apparent. The kerf or groove 12 is of adepth approximately equal to the thickness of the head 8 and extends tothe rounded edge thereof thus forming recesses in said edge atdiametrically opposed points increase the security of grip when saidhead is grasped between the fingers, as when applying the device to use.By this construction it is believed to be apparent that when which theportion or a tight engagement of the portion 3 of the garment iseffected any and all strain occasioned when a pull is exerted on theportion or object 4 will be equally distributed on the portion 3 whichis clamped by the head 2 V the pointed terminal of the shank 9 toproject therethrough in applying the button to comparatively thinmaterial.

. It is believed in View of the foregoing description that a furtherdetailed description of the operation of the invention is entirelyumiecessary. Likewise, it is believed that the advantages-of theinvention will be readily apparent. However, it is to be understood thatthe button may be used for supporting suspenders and in such case, thehead is disposed exteriorly, preferably with the receiving portiondisposed interiorly and adapted to be engaged by the button holed padrepresented by the portion or object 4. incidentally, if the button isused on a coat or like garment, the receiving portion is disposedeXteriorly to receive and retain the 0ppositely disposed button holedportion of the coat, as is apparent.

Still further embodiments on the inventhe hereto appended claim.

Having thus fully described the invention, what is claimed as new anddesired to be secured by Letters Patent, is

A detachable button con'iprising a pair of separable male and femalemembers, the

male member being formed with a head, and

a central externally threaded needle pointed shank, the female memberbeing formed with spaced inner and outer heads and a connecting centraltubular stem providing a passage opening through site sides of saidfemale member, whereby the latter can be reversibly inserted overtheshank, and internal threads in the stem for the detachable engagement ofthe shank therein on the reversing of the button.

In testimony whereof I afliX my signature hereto.
